Mu chitukuko chofunikira kwambiri pa gawo la matenda a makina, kafukufuku watsopano wasonyeza kugwira ntchito bwino kophatikiza modulation signal bispectrum (MSB) ndi convolutional neural networks (CNN) pozindikira zolakwika zamagiya ozungulira a bevelNjira yatsopanoyi ikulonjeza kulondola kowonjezereka, kuzindikira mwachangu, komanso njira yanzeru yodziwira matenda yama gearbox ogwira ntchito kwambiri omwe amagwiritsidwa ntchito muntchito za ndege, zamagalimoto, ndi zamafakitale.

Chozunguliramagiya a bevelNdi zinthu zofunika kwambiri zotumizira mauthenga zomwe zimapezeka mu makina amphamvu kwambiri, ma helikopita, makina oyendetsa zinthu m'madzi, ndi makina ochepetsera mphamvu zamagetsi. Chifukwa cha mawonekedwe awo ovuta komanso momwe amagwirira ntchito, kuzindikira koyambirira kwa zolakwika za zida monga kuphulika kwa dzenje, kuwonongeka, ndi kusweka kwa dzino kumakhalabe vuto laukadaulo. Njira zachikhalidwe zopangira zizindikiro nthawi zambiri zimavutika ndi kusokoneza phokoso komanso mawonekedwe osalunjika.

Njira yatsopanoyi imayambitsa njira yodziwira zolakwika pa magawo awiri. Choyamba, zizindikiro za kugwedezeka zomwe zimapangidwa ndi makina ogwiritsira ntchito zimasanthulidwa pogwiritsa ntchito modulation signal bispectrum (MSB) njira yowunikira ma spectral yapamwamba kwambiri yomwe imagwira bwino ntchito zomwe sizili mzere ndi zosakhala za Gaussian za chizindikirocho. MSB imathandiza kuwulula makhalidwe osasinthika a cholakwika omwe nthawi zambiri amabisika mu standard frequency spectra.

Kenako, deta ya chizindikiro yomwe yakonzedwa imasinthidwa kukhala zithunzi za nthawi yozungulira ndikuyikidwa mu netiweki ya convolutional neural (CNN) chitsanzo chophunzirira mozama chomwe chingathe kuchotsa zokha zinthu za cholakwika chapamwamba ndikugawa mikhalidwe ya zida. Chitsanzo cha CNN ichi chaphunzitsidwa kusiyanitsa pakati pa magiya athanzi, zolakwika zazing'ono, ndi kuwonongeka kwakukulu pamikhalidwe yosiyanasiyana ya katundu ndi liwiro.

Zotsatira za mayeso, zomwe zidachitika pa chipangizo choyesera cha spiral bevel gear chopangidwa mwapadera, zikuwonetsa kuti njira ya MSB CNN imakwaniritsa kulondola kwa magawo opitilira 97%, ikuchita bwino kwambiri kuposa njira zachikhalidwe monga kusanthula kochokera ku FFT komanso njira zina zophunzirira mozama zomwe zimadalira deta yosaphika ya kugwedezeka. Kuphatikiza apo, chitsanzo chosakanikiranachi chikuwonetsa kulimba kwamphamvu ku phokoso lakumbuyo, zomwe zimapangitsa kuti chigwiritsidwe ntchito m'mafakitale enieni.

Kuphatikiza kwa bispectrum ya chizindikiro cha modulation ndi CNN sikuti kumangowonjezera magwiridwe antchito ozindikira zolakwika komanso kumachepetsa kudalira kwambiri ukadaulo wamanja womwe nthawi zambiri umatenga nthawi yambiri komanso umadalira ukatswiri. Njirayi imatha kukulitsidwa ndipo ingagwiritsidwe ntchito pazinthu zina zozungulira makina, monga ma bearing ndimagiya a mapulaneti.

Kafukufukuyu akuyimira patsogolo pakukula kwa njira zanzeru zodziwira zolakwika za Industry 4.0 komanso gawo lonse la kupanga zinthu mwanzeru. Pamene makina odzipangira okha komanso kudalirika kwa makina kukukulirakulira,
